An information disclosure vulnerability in OpenSignLabs OpenSign through 2.37.0 allows unauthenticated remote attackers to map any email address or username to its internal user objectId via the getUserId Parse cloud function. The function performs no authentication before resolving and returning the internal identifier. An attacker can use this to enumerate user accounts and target subsequent attacks.
